Pain points of traditional drone lens protection glass:

Traditional drone lens protective glass has three major pain points:Surface wear in dusty environments(On average, 0.3mm scratches are generated every 200 flight hours), larger onesTransmittance attenuation caused by temperature difference(Decay up to 15% under operating conditions of -20 ℃ to 60 ℃)Atomization phenomenon caused by chemical corrosionThe drone failure rate in coastal areas has increased by 40%. This makes it necessary to avoid these issues in the material properties of the protective glass for drone lenses.


Advantages of using sapphire glass as protective glass for drone cameras:

1. Superb hardness, sapphire has a Mohs hardness of level 9, second only to diamond, and has a scratch resistance six times higher than traditional tempered glass. It can withstand high-speed sand particle impacts;
2. Good optical transmittance (covering ultraviolet to infrared). The infrared band transmittance is 12% higher than that of ordinary glass, and can support the non-destructive transmittance requirements of 8K camera systems;
3. Good resistance to high and low temperature working range; Chemical inertness. Can resist corrosion from salt spray and acid rain. Finally, the lightweight design of sapphire glass also has significant advantages.
